Working principle and safety guarantee of hand chain hoist
Although the hand chain hoist is simple to operate, its internal design ensures the safety and reliability of the lifting process.
· Working principle: When you pull the hand chain clockwise, it will drive the sprocket and internal gear system to rotate, thereby lifting the weight; when you pull it counterclockwise, the brake seat and brake pad are separated, and the weight can drop smoothly under control.
·Safety braking: It adopts ratchet friction plate one-way brake, which is the core safety guarantee. During the lifting process, if pulling suddenly stops or falls, the brake will automatically lock.
The pawl will immediately engage the ratchet wheel under the action of the spring to prevent heavy objects from falling.
